Answer:
C) 8.75%
Explanation:
Number of periods = 4 years
Given return rates = 20%, -10%, 20%, and 5%
To obtain the arithmetic average annual return, add the return rates given for all periods and divide the sum by the number of periods.

Over four years, the S&P 500 index delivered an arithmetic average annual return of 8.75%.
Answer:
Monthly deposit= $164.24
Explanation:
Giving the following information:
Future value= $1,000,000
Interest rate= 0.118/12= 0.00983
Number of periods= 35*12= 420 months
<u>To calculate the monthly deposit, we need to use the following formula:</u>
FV= {A*[(1+i)^n-1]}/i
A= monthly deposit
Isolating A:
A= (FV*i)/{[(1+i)^n]-1}
A= (1,000,000*0.00983) / [(1.00983^420) - 1]
A= $164.24
